I did it! After I published my mushroom balaclava hood pattern, I said I was gonna make a proper hide-your-entire-face-in balaclava, and I did it! Plus...it's a frog. So I consider this a double win.
And it has the cutest little drawstring!
I'm rating this one as an intermediate level pattern. There aren't any complicated stitches, but the construction is above a beginner level. That said, a beginner with strong reading skills who's ready to tackle a tougher project can absolutely take this one on. If you don't have good, even tension, it will absolutely show on this project, so you want to bring your A game.
The face opening uses slip stitch ribbing, but you can use half double crochet instead, or play with hook size to make it larger, if you like. It has a lot of stretch, but I did make mine pretty snug. I have tips on this in the pdf.
